Ring camera alerts are about to get a lot smarter
Ring’s new Video Descriptions feature will tell you what your video doorbell or security camera sees, so you don’t have to watch the video.

Quantum Droplets of Light in Semiconductor Microcavities
Quantum droplets are dilute self-bound configurations of bosons that result from the balance between a mean-field attraction and a repulsion induced by quantum fluctuations. Such droplets have been successfully realized in cold atomic gases and represent a signature of their quantum nature. Here, we predict the existence of a similar droplet phase in a solid-state system, involving polaritons formed from the strong coupling between excitons (bound electron-hole pairs) and photons in a semicondu…

Impact of the history force on the motion of droplets in shaken liquids
Droplets and solid particles in unsteady flows are affected by the Basset-Boussinesq history force (BBH), in addition to stationary viscous friction, inertia, and gravity. The BBH is often neglected, not because this is generally justified, but because its inclusion in calculations is usually difficult. To assess the significance of BBH for particle dynamics, we revisit unsteady Stokes flows around spherical particles or droplets and derive from first-principles the analytical expressions for t…

Generic multicomponent mixtures are multistable
Liquid mixtures of many interacting components often exhibit numerous coexisting types of droplets. An exciting example is the cytosol of biological cells, where diverse droplets, called condensates, are essential for cellular function. However, how much their formation is constrained by thermodynamics is currently unclear. Linear stability analysis predicts that homogeneous mixtures become more robust to fluctuations as the number of components increases, suggesting that droplets do not form e…

More news about the potential collapse of an ocean current, the Atlantic Meridional Overturning Circulation (AMOC) which transfers heat from the tropics to northern Atlantic, giving Europe a much milder climate, controls plankton productivity, and importantly also generates deep ocean circulation by sinking cold dense water.

Thermal transport characteristics of impinging ferrofluid droplets in the presence of a magnetic field
Droplet interactions with solid surfaces are fundamental to natural phenomena and hold significant commercial relevance across diverse applications. While the impingement dynamics of conventional aqueous droplets on solid substrates are well-characterized, the behavior of non-aqueous droplets, particularly those influenced by external force fields like electric or magnetic fields, remains a less explored domain. This study addresses this gap by investigating the impact of a magnetic field on th…

We were in Mt Forest, #Ontario for a performance last night when #tornado warning alarms went off on all the phones. Tremendous amount of lightning, but haven't seen any official reports of damage yet. This is what the sky looked like at 9 pm 😬.

Diverse, Distinct, and Densely Packed DNA Droplets
The liquid-liquid phase separation of biomolecules is an important process for intracellular organization. Biomolecular sequence combinatorics leads to a large variety of proteins and nucleic acids which can interact to form a diversity of dense liquid (`condensate') phases. The relationship between sequence design and the diversity of the resultant phases is therefore of interest. Here, we explore this question using the DNA nanostar system which permits the creation of multi-phase condensate …
